Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this, a...

Open DocumentThe soils ability to grab and hold important nutrient ions until they are absorbed by the roots is just as important as the supply of those initial ions. Soil erosion is the most damaging force against top soil. Soil erosion happens anytime soil is bared and exposed to the elements. Wind and water have a dramatic effect on soil erosion because both events have a tendency to remove the humus particles and carry them away from the soil. The removal can be a slow and gradual process when soil is gradually...

Open DocumentCoastal Erosion Coastal Erosion is a huge problem today and is causing our beaches to get smaller and smaller every year. Coastal erosion is also causing the coast lines to recede and therefore taking away space for which people build on. Even though coastal erosion causes issues it is also the effect of something, Humans! Nature has a way of keeping the world in balance, it creates things such as barrier islands and sand dunes to help protect against costal erosion. However, humans play a...

Open DocumentCoastal Erosion Coastal erosion is a naturally occurring phenomenon resulting from the continuous action of wind and water. Both act to remove small pieces of land from one location and deposit them elsewhere. Weather events such as hurricanes and nor’easters speed the erosion process, as do tidal waves. Currently, rising sea levels resulting from melting polar ice decrease available land as well. While erosion has always been a factor of coastal living, increasing populations along the worlds...

Open DocumentEffects of Erosion Jose Castro ENV/310 July 23, 2014 Wendy Armstrong Significance of Soil Soil is a very vital component for plants that helps them grow and thrive in the environment they are in. Erosion is causing soil to dissipate and it is putting a lot of strain on different plant species. In my paper I will discuss the effects erosion has on the environment and I will provide different ways to eradicate or control erosion. I will also discuss the consequences that erosion will provide...

Open Documentwhen the fertility of the soil is seriously reduced, the people again change their land of cultivation. Thus the essential feature of shifting cultivation is the rotation of fields rather than crops. As a result more and more land are exposed to erosion. (iii) Nature of crop grown In India, as it has been noticed the dry crop producing regions (such as millet, maize, potato, tobacco, cotton and even wheat growing region) of high temperature, low humidity and scanty rainfall are attended by...

Open Documentlandforms of coastal erosion. (25 marker) Most of our landforms on the coastline are formed because of coastal erosion. But firstly it is essential to understand what coastal erosions are. Coastal erosion involves the breaking down and removal of material along a coastline by the movement of wind & water. They are sorted in two categories, Marine processes and Sub aerial processes. A few methods of erosion are; Abrasion, hydraulic action, Attrition and so on. These erosions leads to the formation...

Open DocumentWatershed Management and Soil Erosion Forests provide a buffer to filter water and to hold soil in place. They sustain water and soil resources through recycling nutrients. In watersheds where forests are degraded or destroyed, minimum flows decrease during the dry season, leading to drought, while peak floods and soil erosion increase during the wet season. Flooding along the Baram River in Sarawak has increased significantly since logging began, the major floods occurring in 1979 and 1981.168...
